Channel buttons
The 16 buttons across the top of the screen represent each channel.

- Right-click: a menu for switching Engine (FM / SSG / Off) and Output (A / B / C / D).
| Element | Meaning |
|---|---|
| Large number in the lower-left | Channel number (1–16). Matches the MIDI channel. |
| Small text in the lower-left | Engine type (FM / SSG / Off). |
| Colored badge in the upper-right | Output bus (A / B / C / D). |
